HBO Now Debuts on Apple Devices

The service, which costs $14.99 a month, is now available through Apple or Optimum Online.

HBO's standalone streaming service is here.

The cable network announced Tuesday morning that HBO Now is available to consumers through Apple devices or Optimum Online, the Internet TV portal for Cablevision.

People can subscribe to HBO Now, which costs $14.99 a month, via Apple through the Apple TV or by downloading the app on their iPhone, iPad or iPod touch. Anyone who signs up during the month of April will receive a one-month free trial of the service. Once someone has signed up on an Apple device, they can watch HBO Now on any device at HBONow.com.

Optimum Online customers can sign up by phone or via the website. Once they have done so, they can watch on Apple devices or through the HBO Now site.

HBO Now offers similar programming as HBO Go, the streaming TV service that HBO offers to cable subscribers. It will offer more than 2,000 titles, including current series such as Game of Thrones, Silicon Valley and Veep. It will also offer classics such as TheSopranos, feature films, and documentaries and specials.

HBO unveiled the new service in March at Apple's Watch event in San Francisco. Apple is the exclusive digital launch partner for HBO Now. The network says it is in discussions with its existing network of distributors to add more partners, and that HBO Now is expected to become more widely available on over-the-top services after the exclusive agreement with Apple ends.
